Are humans superior to other forms of life? If superiority means being of a higher rank than another, then I do not think we are superior because just like all animals we depend on other organisms to survive.  Therefore, we are all of the same rank. 

However, if superiority means having a “competitive advantage” (dictionary.com), then, yes, I do think we are superior to other organisms.  The humans’ ability to produce language, culture and technology, has given us the “competitive advantage” over all other species.  What we are unable to do naturally, we are able to compensate for with our unique “ability to try things out” (Grobstein).  For example, we are unable to withstand extreme temperatures, but we have developed heaters, air conditioners, insulated shelters and clothing that have enabled us to live comfortably in all types of climates.  Therefore, depending on one’s definition of superiority, humans are either superior to other organisms on this earth or not.
